Abstract
An embodiment is an inductor that may include a slotted magnetic material to decrease eddy currents therein that may limit the operation of the inductor at high frequency. An embodiment may employ electro- or electroless plating techniques to form a layer or layers of magnetic material within the slotted magnetic material structure, and in particular those magnetic material layers adjacent to insulator layers.
